I'm waiting on my pair. We kickstarted (?) two of them. Any day now...

Yes, we'll be renting them.

I'd rent one for a weekend for sure.

 

I received an email today to say mine is on its way. Kind of ironic that it will be arriving in time to connect to my Fox Float X2 that I'm not supposed to ride.

 

Showed up last night!

Can you log two sensors at once? The manual leads me to believe it's only one at a time.

 

I'm not entirely sure about that yet. The first two thirds of my first ride, I had it set to log on the rear shock, but when I swapped to the fork it said it already had sufficient ride data to make suggestions.

 

We got ours on Monday. You can log data on both (I think) but can only view one at a time with a single device. I guess you could have two phones or something...

I've yet to RTFM or even ride with them. I got so far as to hook them up to the bike and discover the bluetooth with tablet and phone but nothing else.

More later...

Received mine last week. Posted an unboxing and a first ride review on YouTube :

It basically said my shock settings were good, which is reassuring. I haven't had time to ride since last week to try it on the fork or intentionally screw up my shock settings and see if it can fix it. So far so good though.

I'm considering renting it out, it's a cool toy but seems like its use is somewhat limited unless you're getting a new bike every year or tuning for a specific race course or something.

 

So far working great with the CCDB, but having some issues with the Ohlins fork. Cal status continues to show up red, even after swapping shockwiz units. Tried multiple times but it doesn't seem to like the fork. I know shockwiz specifically mentioned certain forks that weren't compatible, which didnt include the ohlins, but I'm not sure if the fork is constructed in the same manner as the forks that don't work like MRP and trek DRCV. Damping adjustments seem to get good suggestions, but it keeps calling for air to be taken out. I've tried taking out air far past any reasonable sag measurement and it still calls for more. The calibration seems good, as I experimented by measuring out specific points and compressing the fork to them. Every time the app displayed exactly the right %. I have an email in to quarq. Eagerly awaiting a reply.

 

I got a chance to run mine Saturday. Said rear shock was good, just need to drop down one size volume reducer (Fox).

I didn't set up the fork correctly so that didn't work. I rode it at our local beginner trail yesterday and it didn't get enough data. That was my assumption but I wanted to be sure.

We will absolutely be renting them out so we are trying to get up to speed quickly. We have a suspension clinic here Thursday evening. We'll be showing people the interface, set-up and outputs. I think it'll be useful but it's just a tool. You'll still need some human interaction to ensure that you get the right set-up. It's data, though, so we'll be layering our experience on top of the numbers. It will help make suspension set-up way less magical and help people understand what is happening.

I used mine on the rear Fox shock on my Niner RKT 9 RDO. The set up went smoothly. I rode with the shock in the open setting and the Shockwiz confirmed that the settings I had were good. The only suggestion was increasing low and high speed compression, which really isn't an option on the Fox rear shock except for changing from open to trail mode.

Next up is testing the front fork, a Fox Factory 32 with FIT4 damper. I think this fork could still use some dialing in, so curious to see what the Shockwiz suggests.

So far I have to say this is a pretty cool little device.

If someone is ready to rent one out, please pm me. Very curious about checking it out.

 

If the shockwiz says your shock settings are good, try changing your settings and go to the same course again to see if the shockwiz suggests the same settings you had before.

 

This is what I want to hear about as well. I'm curious how well it actually works and have entered seen anything that tests this. I really want the test on a shock or fork with high and low speed compression, not a 3 setting compression damper like. Let's see how accurate these things actually are.

 

I'm pretty confident that this device can measure the position of the suspension as a function of time quite adequately. What to do with that information is the complicated part. I'd like to know a lot more about how it analyzes the data, presents that information, and uses it to make recommendations.

 

That's the important part. I'm skeptical on it. Most reports show no changes needed, which I find hard to believe. Time will tell, a thorough test/review will hopefully come out.

Seeing that the software and the firmware are both updateable I would think any algorithm issues would be something that could be easily solved. It would be fun to see if someone can get a live data stream and overlay it with GPS, power, gear selection, etc.

 

Would love to give this a spin. Renting it out seems like a smart idea.

 

I think we'll have ours available starting next week.

After tuning the rear shock on my RKT 9 RDO, I ran the Shockwiz on the front. My build has a Fox Factory 32 with FIT4 damper and 100mm travel. I've only had the bike a short while and was still working on dialing in the front, so it was a good opportunity to get some feedback from Shockwiz.

The initially report back after my first 1 hour loop on a local cross country trail with roots, a few shorter climbs, and some smaller rocks was consistent with what I was thinking. It recommended less air pressure, more rebound dampening, and adding a spacer. I didn't have an extra spacer on hand (my shock is supposed to ship with two installed but I haven't doubled checked that it did), but I did lower the pressure (down to 85 psi) and added some rebound dampening. I took an hour lap and the feel was improved but I do blow through the 100 mm travel at times. The feedback after the changes was still to add a spacer and drop psi further. Rebound was now good.

I've ordered some Fox spacers and will add them and hopefully retest before winter hits Ohio. I spoke with SRAM and they told me it will be important to run though the calibration again after the spacers are added.

I'm also planning to get a ride in on my Salsa Beargrease fat bike equipped with a Bluto. It will be fun seeing how the Shockwiz tunes that set up.

Yes, very curious to see what it thinks of fat bike tires.

 

Hello Everyone,

Just had a chance to read through the thread and figured I could add some useful information. If anyone has any specific questions please ask, I will do my best to stay on top on them.

There seems to be a little confusion as to how ShockWiz works in regards to data storage, transfer and so forth. Below is a article that we will posting to www.ShockWiz.com in the near future, but figured it was worth posting here now.

As I said, if there are any questions or concerns that pertain to ShockWiz let them fly.

Data storage: All data collection and analysis is performed within the ShockWiz device itself; no computation occurs within the app. The app is only a means to display the collected information and for you, the user, to interact with the device to perform a task such as a calibration or to start a new session. Since the data is stored directly on the ShockWiz device it is not necessary to carry your phone during a ride. However, once you have the ShockWiz app open and connected to your device you can check the results at any time. This could be at the end of a segment, the end of a ride or in three weeks time, it doesn't matter. Your data will be saved until a new session is started.

Using two devices: If you have a dual suspension bike, then it is beneficial, but not essential, to use two ShockWiz devices simultaneously. The process of using two devices is very similar to using one. You simply have to connect to each device individually to set them up and review the results. To switch between devices, simply tap the device name at the top of the app page and select your other device from the list. On some phones it may be beneficial to first disconnect from the current device before you connect to the other.
There is no communication between ShockWiz devices, only from each device to the phone/App. Tuning, however, does become much faster with two devices because you are capturing twice the data at once and there is no need to swap from the front to the rear. Typically, but not always, both the front and rear of a dual suspension bike should be set up and tuned with the same Tuning Style.

Tuning Styles
When it comes to tuning mountain bike suspension, there is a lot of variance in how people like to ride and the different styles of bikes for different terrain and disciplines. The Tuning Styles within the ShockWiz algorithms try to account for these variances.
Some people like to use every last millimetre of travel, while others like to have a large travel buffer in reserve for any unforseen obstacles. Additionally some riders like to have the bike be lively underneath them and be able to 'pop' off small mounds and kickers, where others like the wheels to be very planted to the ground and controlled.

There are quite a few things that change between Tuning Styles, but the following descriptions give an overview of the main differences.

Efficient - Focused purely on pedalling efficiency. Efficient will keep you higher in your travel and minimise pedal-induced suspension bob. Efficient produces the firmest suspension tune.

Balanced - The middle ground that provides an overall compromise between traction, suppleness and pedalling efficiency. Balanced serves as the default ShockWiz Tuning Style.

Playful - Similar to Balanced but with a more lively feel to give the bike 'pop'.

Aggressive - Focused on a supple and active ride, caring very little about pedal-induced suspension bob. Aggressive makes sure you use all of your travel and produces the softest suspension tune.

 

As I said, if there are any questions or concerns that pertain to ShockWiz let them fly.

Hey Alex, does this work with a lefty fork? Thank you for clarifying things in this thread

 

Hey Alex,

Does the shockwiz work with the new MRP Ribbon fork or the Ohlins?

 

Hey 7four8,

Unfortunately it looks like a 'No' for both.

I am not super familiar with the Ribbon air-spring design, but everything I can find shows that it uses the Ramp Control Cartridge which is not compatible with ShockWiz. The Ramp Control Cartridge functions by altering the air volume of the positive air spring chamber during compression, which creates a variable compression ratio making it a no go for ShockWiz. If the Ribbon where used without the Ramp Control Cartridge it would be fine.

Same goes for Ohlins. The RXF34 and RXF36 suspension forks use a 3 chamber air spring; 2 positive, 1 negative. The second, smaller positive chamber makes for a variable compression ratio in the larger air chamber measured by ShockWiz.

Compression ratio is a fundamental piece of the travel percentage calculation and must be constant.

Alex@Quarq

 

Ah ha! Funny, right after I sent that post I found the powerpoint presentation on how the RXF fork operates on the specialized dealer website and immediately understood why the shockwiz isnt combatible. I never knew that piston was floating. Definitely explains a lot, and yes, the device constantly asks for air to be removed from one or both chambers. I have seen it occasionally read OK for one or the other chamber if I start a new session and only ride downhill type trails. I've found the rebound suggestions and low speed compression to be useable, but even with the HSC turned all the way down, the shockwiz always says its too high. I'm a bigger guy (6'3" 250lbs) and more often than not am on the high end of damping settings for factory tuned stuff.

I had my suspicions all along that the fork wasn't compatible, but that's actually relieving to finally hear it straight from you cause it's been a struggle figuring out how to get it set up. No worries about the email thing, I figured something must have happened with the form.

Other than that debacle, I'm totally stoked on the performance of the shockwiz. It has helped tremendously with my CCDB.

The only "gripe" that I have at this time would be: since I have climb switches, I'm really not too terribly concerned with the damping settings for uphill stuff. I wish there was a way to "pause" the shockwiz and not have to start a new session so that I could exclusively gather data on the downhill sections. I have a lot of seated climbing sections that I feel kind of skew the data.

Thanks, Alex!

Chris

Edit: Thinking more about what you said, and that you emailed Nigel about it. Are you thinking there may be some formula for a pressure to set the ramp chamber for calibration? I'll have to ponder that one after my morning coffee. Given that the volumes of the ramp and main are different, I'm not sure it would be as simple as a % difference. That, and any change to either chamber would require a totally new recalibration instead of just baseline, which would be a huge pain.

 

Hey Chris,

ShockWiz assumes that certain things are constant, or I should say, ShockWiz requires that they be constant in order for it to work properly. In the situation with the RXF air-spring, ShockWiz has no way of knowing whether or not the compression ratio is changing, how much it changing by, or for that matter at which point in the travel the change occurs. In order for it to know any of this you would need a Wiz monitoring each positive air chamber, likely have them communicate to one another, and there would probably have to be some special firmware specific to the RXF models. There are so many variables involved with that there would be no easy way to make it work. So no, this is going to work anytime in the near or distance future.

I just mentioned getting Nigel involved as he was also unfamiliar with that spring layout. I am pretty sure that you and I both have access to the same document, which I shared with him. Once he saw the layout he confirmed that it is not compatible with ShockWiz.

The whole "Press start to record" or ability to "pause" isn't a bad idea, it just opens up the opportunity to forget. I am sure you have missed hitting start on a Garmin or other head unit and understand how frustrating it is to do. What you should do is just experiment and see what happens. You should see how your suggestions are impacted if you let the session run after climbing when the switch is used; and then on the same section when it is not used. ShockWiz wants to see you pedal so just because you're trying to set things up for descending doesn't mean you can't record on the ups. I wouldn't expect it to make a huge difference, especially if you are climbing on relatively smooth trail/road.

The main thing that will change when climbing with the switch 'on' vs 'off' is pedal induced bobbing. With it off there will be more, which ShockWiz will try to correct with firmer (increase) LSC. If the switch is on, then Shockwiz might not even see enough movement (change in pressure) to make any suggestion at all. Depending how firm that shock becomes with the switch on, it may already act like a "Pause" button, as it may restrict movement enough that ShockWiz doesn't even realize you're riding.

Alex@Quarq

P.S. It should be known that everything that I just said about the climb switch goes against what Nigel would say. And in the end he is correct, flipping on a climb switch is a damping change (ShockWiz has no idea when you make a change which is why the "New Session" feature exists) and does mean you should start a new session. However, if you able test it out and (if in your situation) flipping it on mid-session doesn't noticeably impact your suggestions I say run with it. If it does, then don't do it.

 

Thanks again! I really appreciate all the info.
